SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 507,338, dated October 24, 1893. Application filed April 28, 1892. Serial 110.431.036. (No model.)

To @ZZ whom it may concern:

Be it known that l, HORACE W. TIBBALs, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in self heating sad irons, and the invention consists in the peculiar construction, combination and arrangement of parts, all as more fully hereinafter described.

In the drawings Figure 1 is a side elevation of my improved sad iron. Fig. 2 is avertical central, longitudinal section thereof; Fig. 3 a cross section on line -x Fig. 2; Fig. 4 a bottom plan of the upper part of the iron and Fig. 5 a top plan of the lower part of the iron.

My improved sad iron is made in two parts A and B, (shown in Figs. 4 and 5) the part B containing the combustion chamber, burner and auxiliary heater, and part A consisting of the reservoir, handle, vapor tube and jet valve, the specific construction of which is as follows:

C is the reservoir which is substantially U- shaped and has the horizontalportion D and the two vertical end extensions E and E.

F is a spur upon the side of the extension E', and G a lug on the top of the extension E.

H is a handle preferably made of Wood apertured at one end to engage on the spur F and having the recess at the other end in which the lug G is adapted to engage, and to which it is secured by means of the fastener I.

H is a fill opening in the top of the eXtension E normally closed by the screw cap l.

J and J are bosses upon the lower side of the reservoir.

K is a plate forming the top for the combustion chamber secured to the bosses J and J L is a downwardly projecting tube connected to the reservoir through the boss J and having the lateral bend L', the rearward extension L2 forming a vapor tube, and the lateral bend L3 connecting it to the jet tube L4 in which is the needle valve L5.

M is a shield preferably made of asbestus or other suitable non-conductor of heat which is secured below the plate K leaving a small air space M between said shield and plate.

'Ihe part B consists of a hollow casing containing the combustion chamber N having the apertured side walls O and rear wally P.

Q is the burner located within the combus tion chamber and formed of an outer tubular casing ct within which is inclosed the com mingling tube b extending from the rear end of the casing to the middle and havinga down turned end. c are slots or apertures in the casing a. The burner is supported a short distance above the bottom of the hollow casing by the lugs d at each end. The thickness of the casing directly under the burner is preferably greater than at any other part of the bottom.

R is a cavity or basin formed at the side of the commingling tube in which a piece of asbestus or other porous non-combustible material is placed.

When the two parts A and B are secured together the relative position of the burner and vapor tube is such that the latter passes along one side of the burner while the lateral bend L8 will bring the jet tube L4in line with the center of the commingling tube so that the jet will be directed into said commingling tube.

S is a partition which separates the jet tube L4 from the rest of the combustion chamber inclosing it within a chamber S.

S2 is a slot in the rear wall P of the hollow casing through which the squared end of the valve stem projects.

T is an aperture in the plate K, and U a cover normally closing said aperture.

In practice whenv it is desired to use the iron a small quantity of alcohol is first introduced through the aperture T into the combustion chamber where it becomes absorbed by the asbestus or other porous material in the cavity R. The operator then applies the match and by the burning of the alcohol the vapor tube L2 is heated sufficiently to generate gas from the liquid fuel (such as naphtha or gasoline) which has been previously introduced in the reservoir C, and from there passed through the tubes LL into the vapor tube. As soon as the gas is generated, by opening the valve L5 the jet is directed into the open end of the commingling tubeb which conducts the vapor mingled with the proper amount of air into the center of the burner,

IOO

where the down turned end of the tubeb will distribute it uniformly to all parts of the casing, and passing through the apertures c it will become ignited on the outside. The eX- tra thickness of metal below the commingling tube prevents the over heating of that portion of the iron. The shield M together with the air space M' at the top of the combustion chamber will prevent too great a loss of heat from radiation, but a sufficient amount will nd its way to the reservoir C to expand the liquid contained therein and keep up a constant feed into the vapor tube.

By inclosing the jet tube in the chamber S the jet is protected from becoming ignited by the dame of the burner and from any injury it might receive were it placed outside of the casing.

\Vhat I claim as my invention is 1. In a sad-iron, the combination with a hollow base, of' a superimposed reservoir, a burner in the base, non-combustible absorbent material in the base, a feed opening formed in the base a cap for the opening and a vapor tube above the noncombustible material, substantially as described.

2. In a self-heating sad-iron, the combination with the hollow casing having the combustion chamber formed therein, of a vapor burner within said combustion chamber, a commingling tube within said burner, a vapor tube arranged at the side of said burner, and a supplementary heater for said vapor tube consisting of a basin formed in the casing below containingaporousnon-combustible substance adapted to be saturated with infiammable liquid, substantially as described.

3. In a self heating sad iron, the combination with the hollow casing having the combustion chamber formed therein, of a reservoir arranged above said combustion cham ber having upward extensions E and E one at each end, the spur l, the lug G, the handle I-I, and the fastenerI passing through the handle and lug, substantially as described.

4. In a self heating sad iron, the combinan tion of the hollow casing having the combustion chamber N, the partition S and chamber S', the burner Q in the combustion chamber, the commingling tube b having the downturned end, the vapor tube L2 at the side of the burner and the jet tube in the chamber S', substantially as described.

5. In a self heating sad iron, the combination of the hollow casing, the combustion chamber N, the partition S, the chamber S', the burner Q, the commingling tube b, having the downward turned end, the vapor tube L2 at the side of the burner, the lateral bend L3, the jet tube L* in the chamber S', the reservoir C having'extensions E and E', the handle II, the shield M, the air space M', the aperture T and cover U', substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
